The dominant compounds in giant panda milk in Phase 2 and Phase 3 of early lactation.

The 20 most abundant liquid chromatography-high resolution mass spectrometry (LC-HRMS) features in Phase 2 and Phase 3 of lactation together (7 to 21 days cumulative post-partum) milks. Relative abundances were estimated from areas under LC peaks. The compounds are listed in the order of their LC retention times (Rt). Italicised names indicate non-proton adducts and complex ions identified by MZMine 2.10, and confirmed by manually checking the raw LC-HRMS data. The metabolite annotations are based on the Metabolomics Standards Initiative (MSI) identification levels; level 1, retention times matched with authentic standards (labelled as ST); level 2: identified by MS/MS (labelled as MS); level 3: accurate mass; and level 4 unknown. The metabolites identified at levels 1 and 2 are also labelled with the compound identifiers (CID) codes from the PubChem database.
